The gift vouchers will be awarded to the winner of the national competition which would be decided by who sells the most unique burger creations, who has the best recipe and who has the best counter display.

"I would like everyone in Rocky to come down and support us, it's nation-wide against some pretty foreign meats,” Ms Ketu said.

Two of the more unusual Northern Territory burgers Rockhampton will be competing against will feature barramundi fillets and lean water buffalo patties.

Ms Ketu said she wasn't focused solely on winning the competition.

"For me it's to get my team involved and bonding because I've got new staff members and they're pretty enthusiastic,” she said.

Staff member Paula Allen, who has worked for Puma for the past four years, was so enthusiastic that she planned to come in on Sunday to build Big Feed Burgers on her day off.

"I'm just coming in volunteering to help, I'm going to be out the back preparing,” Ms Allen said.

"I am excited, just to get a bit of pride in the place, a bit of community spirit.

"Let's do it, let's beat the other states, we can do it.”

Don't miss out on trying a Big Feed Burger this Sunday for only $9.95.
